Had a fantastic day, just missed the big powder dump but the hill was still amazing. It was also alpine demo days and the selection of gear to try was very good. The line ups were a bit long but that's to be expected for a weekend with a huge dump of snow, mild temps and no wind. Can't wait to go back again next season.
